WPB Editor shows blank page instead of the site content.

Site snapshot was restored recently.


There is an internal issue in Parallels Web Presence Builder 10.4, which causes a site corruption in case if the snapshot with invalid data was restored.

The issue was fixed completely in WPB 11.x.


The preferred solution is to upgrade to the version where the issue was fixed (11.5 is recommended).

Alternatively, you might install a patch for 10.4 version. To do so, please follow the below steps:

  1. Create a backup of the following files:

/usr/local/sb/include/SB/BRU/BackupStream.php /usr/local/sb/include/SB/BRU/Restore.php /usr/local/sb/include/Base/Utils/String.php

  1. Download the archive with patched files, extract them and replace the files that were backed up in the previous step.

  2. Restore site snapshot.
